TS2570 Is downloaded mavericks and installed. I cannot boot up, it hangs on the grey screen with the apple logo

Will not boot

Here are some suggestions based on my recent issue with unable to get Mavericks up after upgrade - The Apple geniuses just simply couldnt figure this one out...despite it being in their shop for 3 days (They probably did not look at it...and asked if they can just wipe out everything and install fresh...i had said NO):
Restart computer and hold Cmd+V when you hear chime. This will start the computer in Verbose mode.
See the messages and see where the system boot fails. In my case, it was some backtrace IOStorageFamily issue with com.paragon-software.
Google may be able to solve your Apple issues - just type the error message in and see if you get any useful suggestions. in most cases - this would be some faulty 3rd party drivers.....
In my case, it was something stupid i had probably installed....I had to boot to safe mode (Hold Shift at boot chime) - open Terminal, delete the folder com.paragon-software.kext from System/Library/Extensions....that fixed the problem. Mavericks is working great now....
Let me know if your debugging thing works...

Hi,
I had the power supply connected when I attempted it previously but even so my problem occurred. My rom is different and so I still need to update it.
Thanks
I wanted to mark your answer helpful too but I didn't know that I could only put it for 2 answers. Sorry
That was good advice by G-N and s/he is correct about it. Unfortunately, ASC allows only 2 "helpful" and 1 "correct" marks per thread.

Apple - Support - MacBook Pro
Mac OS Version builds
When did yours come out? what does the above show as model and minimum build?
You should have yoru OEM OS X DVD, not one from another Mac, or retail, though the last retail OS X DVD was a year ago 10.6.3.
If it installed, I don't see an issue unless the drive had corrupt directory etc.
What you need to do is repair your boot drive or restore from backup.

TS2570 On start up of my new iMac it locks on the grey screen with the apple logo and the progress wheel spins. Boot up in safe and this is where it stopped at "BootCacheControl: Unable to open /var/db/bootcache.playlist: 2 no such file or directory. "

Reinstalling MacOS does NOT fix the problem for me. I'm still searching a solution !

I have a Macbook and I left it unplugged. It started up slowly when I plugged it in again, but it seemed fine. Once it started charging I shut it down so it would be easier, but now it will not go past the grey screen with the apple. What do I do?

I have Snow leopard on my computer, and I tried to do a hard restart as an article suggested, but it did not work. I also tried cleaning out the PRAM.
The only things I did last night:
-cleaned the history of Firefox out, including cookies
-let it unplugged all night
-plugged it back in the morning, it took a long time to figure itself out, but eventually the time was correct and I got on the internet for a bit
-shutdown the computer since I was going out and thought it would help the computer charge
-came back, tried to turn it on, and found that it would not go past the grey screen the apple on it and the spinning wheel even though I left it for 20 minutes or more
-tried turning it off and on to no avail

Before doing a reinstall, which may not be needed at this point,
Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk.
You could have some directory corruption. Let us know what errors Disk Repair reports and if DU was able to repair them. This could just be a start in repairs and you may need a better utility to finish the job.
Then Repair Permissions.
No need to report any Permissions errors........we all get them.

Sounds like you may have a harddrive issue. You are probably going to need to get that changed out and then install the OS X again to get it going.

Hello my Mac Air is frozen on the grey screen (with the apple symbol, sleeping mode, restart-and off button), once you turn it on.

hello my Mac Air is frozen on the grey screen (with the apple symbol, sleeping mode, restart-and off button), once you turn it on. I Can`t press any button.My Mouse still works. Battery is charged. Alt-cmd-escape doesn`t work It even after a forced shutting off, the problem is the same.   what should i do? Thank you for your help.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
     a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 8
This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. The battery is distinct from the main battery of a portable. A dead logic-board battery can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

I am going to sell my second generation ipod touch, so i resetted it to factory defaults. It said it would take up to an hour, and i patiently waited. But when the black and white loading bar completed, the ipod went to the black screen with an apple logo

I am going to sell my second generation ipod touch, so i resetted it to factory defaults. It said it would take up to an hour, and i patiently waited. But when the black and white loading bar completed, the ipod went to the black screen with an apple logo on it. Sounds about right, right? But now, there is a processing circle on top of the logo, but the circle spins once, and stops at about halfway to the bottom. It just stays there, and about every half to one hour it becomes a white screen and starts all over again. (not the loading bar part, just the circle). I've tried holding the power and the home button, and it works, but it just goes back to the circle screen with the apple logo. HELP PLEASE?

Try:
- iOS: Not responding or does not turn on
- If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

My macbook pro will not boot. It gets the grey screen with the apple until the bar is half way across and then shuts down. The only screen I can get to is in safe mode and I don't know what to do with that

There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.a. Boot into Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.

This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
